Elbow calibration device and elbow calibration method

The invention relates to the technical field of steelmaking equipment, in particular to a bent pipe calibration device and a bent pipe calibration method.The bent pipe calibration device comprises a calibration platform, a height-direction calibration mechanism and a width-direction calibration mechanism, a height-direction reference and a width-direction reference are arranged on the calibration platform, the height-direction reference is arranged at one end of the width-direction reference, and the width-direction reference is arranged at the other end of the width-direction reference; width-direction benchmarks are arranged on the two sides of each width-direction benchmark, the height-direction benchmark and the width-direction benchmarks serve as references, and rapid calibration of the bent pipe can be achieved through the height-direction calibration mechanism and the two width-direction calibration mechanisms. The calibration platform is further provided with a large arc section adjusting auxiliary me
